I purchased my Silverado new in 2015 .  It’s a V-6 crew cab 1500 4x2.  I am noticing that it seems to be shrinking, getting closer to the ground.  Not as tall as it was when I bought it.  So today I googled the specs and I find that it’s supposed to be 74” (+\-).
 

So I measured it and it is just shy of 71”.  It has 298,000 miles and I’ve replaced the tires a couple times but always with the exact match to the tires that came on it.  I’ve had the struts and shocks replaced once and most recently all the ball joints and control arms.  
why is my truck shrinking?

If the leaf springs in the rear have sagged over time, that will drop the height a decent amount.

 

Most 2WD trucks have a decent rake to them too, the rear is usually up higher by like 1.5-2 inches.

I can accept that the rear leaf springs are sagging but how does that affect the front?  Is there some kind of leveling system?  Maybe?

Nothing from the factory.

 

You would have wanted to measure the stock fender to ground height when it was new and compared it to what you see now. My point was that if the rear is sagging 1-2 inches that is going to bring the front and rear more level and reduce the overall height by roughly the same amount depending on exactly where you measure from.

 

We have two 2016 4X4 crew cab trucks at my house right now, I took measurements from the stock truck as mine is lowered. Overall height is roughly 73in inches. The shark fin antenna is likely factored into the factory specs and I am not including the height of that. The front fender to ground is 36 and 1/4in and the rear is 38.5 inches ground to bottom of the fender. These are taken from the passenger side and I have no clue how much fuel is in the tank. A full tank of gas will sag the drivers side.

 

See what your measurements are compared to that.

Thanks, tomorrow I will compare your 4x4 measurements to mine.  I’d be surprised if the shark fin is calculated in to the spec height but who knows in this world we live in.  Thanks for your time sir.

When was the last time you got an alignment? If the toe is off maybe 1/2 in difference not 3 in, but you said that you just had the front suspension replaced. Was it done correctly?

Anything on the truck from the factory will be factored in.

 

If they don't, and someone drives under something then "rips" it off, they would have a lawsuit on their hands.

    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that. 
    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
